Filed: 1973-04-06
Abstract: 1409461 Pump plunger seals UNION CARBIDE CORP 6 April 1973 16638/73 Heading F2B  The plunger 104, Fig. 1, of a high pressure pump 101 is sealed by means comprising circulating sealing liquid under pressure to an annular clearance seal zone 110 surrounding the plunger, the zone being sealingly separated from the pumped liquid chamber 103 by a floating piston whereby the sealing liquid is subjected to the pressure of the pumped liquid in the chamber 103. The piston is sealed in a chamber in the pump body 102 by seals 108 and 109 and divides the chamber into two parts 106a and 106b communicating respectively with the pump chamber 103 and via the seal zone 110 with a leakage chamber 111 sealed by seals 112 and connected by a conduit 113 with a sealing liquid reservoir 114. A pump 115 pumps liquid from the reservoir to the zone 110 at a constant pressure controlled by a regulator 119 to be slightly above the minimum pressure of the liquid in the chamber 103 during the suction stroke. In operation, during the compression stroke the pressure of the pumped liquid moves the piston 107 to the left to impose the same pressure on the sealing liquid in the chamber part 106b and in the zone 110, and during the suction stroke, the piston is returned to the right by the pressure of sealing liquid supplied by the pump 115. A vent passage 120 and valve 121 may be fitted. In a modification, Fig. 2 (not shown), the piston (207) is located in a bore in the pump body (202) and the seal chamber parts (206a and 206b) communicate with the pump chamber (203) and seal zone (214) through passages (205, 213) in the body. In a further modification, Fig. 3 (not shown), sealing liquid is supplied to the seal zone (320) through a passage (316) and a spring-loaded valve (315) in the plunger (304). In the embodiment shown in Fig. 4, the seal zone 416 is separated from the pump chamber 403 by a seal ring 419 and the floating piston 407 is housed in a chamber 406 external to the pump body 402 and connected to the chamber 403 and zone 416 by conduits 405 and 414, 417 respectively.

Patent GB-571566-A (GB)
Title: Improved manufacture of artificial yarns
IPC: D01D7/00
Filed: 1943-10-14
Abstract: <PICT:0571566/IV/1> <PICT:0571566/IV/2> A twistless nylon yarn is obtained by twisting a plurality of nylon filaments, obtained by melt-spinning, cold-drawing the twisted yarn so formed and collecting the drawn yarn on a spindle rotating reversely to the twist of the yarn so that when the yarn is unwound from the spindle it is substantially free from twist. The reverse twisting is substantially equal in magnitude to the initial twist divided by the draw ratio. The unwinding from the bobbin may be such as to involve a twist, i.e. by direct over-end withdrawal, or such as to involve no twist, that is, by parallel withdrawal.  In the former case, the residual twist of the yarn on the bobbin is such that the over-end withdrawal nullifies it.  In the latter case, the yarn on the bobbin is free of twist.  The twistless multifilament yarn may be used for covering electric wires and cables.  As shown in Fig. 1, nylon filaments collected from a spinneret and having no twist are taken from bobbin 1, passed through feed rolls 3, 4, guide 5, and traveller 6 on reciprocating ring 7, and are wound and twisted on bobbin 8.  As shown in Fig. 2, the twisted yarn is taken from bobbin 8, passed between feed rolls 10, 11 and stretched by means of roll 13 and separator roll 14.  The draw ratio may be 4 : 1.  The twisted and drawn yarn is taken up on the untwisting bobbin 18.  Specification 514,821 is referred to.
